Are arranged vertically at the four corners of the basin 54 of the pool and are attached to the inner surfaces of the rear and front rims 52 and 53, and a pair of guide members 21 are inserted to guide the floating table 20 in the vertical direction. Guide rail 22, a stopper member 23 as a stopper that is attached to the rear and front wall portions 52 and 53 of the bathtub 5 and prevents the upper surface of the floating platform 20 from rising above the upper surface of the bathtub 5, and the floating platform. It is composed of an air valve 24 that adjusts the air in the air reservoir 20a formed inside 20 to escape to the outside, and a backrest 25 that is attached to the upper surface of the floating base 20 on the front side.

As shown in FIG. 5, the pedestal 20 has a box-like shape with its lower surface opened, and is formed of a plate-shaped member that is light and does not easily deform. This float 20
It is composed of an upper support plate portion 20b and a side plate portion 20c which extends downward from the outer end portion of the support plate portion 20b and forms an air reservoir 20a which is open to the inside with the support plate portion 20b. The four corners of the floating table 20 are shown in FIG.
As shown by, a concave portion 20d for guiding the hot water H in the hot water reservoir 54 of the bathtub 5 to the upper side of the float 20 is formed, and the guide member 21 is attached to the side plate portion 20c on the concave portion 20d side. . Further, an air hole 20f for letting air in the air reservoir 20a escape upward through the air valve 24 is formed in the rear portion of the support plate portion 20b of the floating table 20.

The pair of upper and lower guide members 21 are fitted into the concave guide rails 22 so as to be in close contact with each other, and are movable only along the guide rails 22 in the vertical direction. Therefore, even if a force is applied to the end of the pedestal 20, the pedestal 20 rarely tilts.

The air valve 24 is attached to the back surface side of the support plate portion 20b in a state where one end side thereof is guided to the air hole 20f side of the floating table 20 and the other end side is in communication with the air reservoir 20a, and is not shown. A signal from the controller causes the air reservoir 20
It operates so that the air in a is escaped above the floating table 20.

Next, a bathing procedure for bathing in the bathtub 5 to which the bathing auxiliary device 2 is attached will be described. First, a bubble J for a bubble jet is generated from the air nozzle 55a, and a sufficient amount of air is sent into the air reservoir 20a of the floating table 20, and as shown in FIG.
The upper surface of 0 against the stopper member 23,
The upper surface of 0 and the upper surface of the bathtub 5 are flush with each other. In this case, the air reservoir 20a is slightly pressurized above atmospheric pressure so that the float 20 does not move almost downward even when a person rides on the float 20.

Next, as shown in FIG. 8 (a), the bather M sits on the floating table 20 on the right wall portion 51 side of the bathtub 5, and then, in FIG. 8 (b). As shown, while placing the left and right feet on the float 20 in the hot water reservoir 54 of the bathtub 5,

It should be noted that the bather M can also sit on the pedestal 20 so as to raise his / her upper body and take a bath. When a healthy person takes a bath, the stopper member 23 may be removed and the floating table 20 may be pulled out upward. Of course, in this case, the bubble jet device 5
The use of 5 is also possible.

As described above, the bather M can use the bathing assisting device 2 to enter and leave the bathtub 54 of the bathtub 5 in a comfortable position lying down, so that the weakened body with weakened muscle strength can be used. Even a caregiver can easily take a bath without imposing a heavy burden on the caregiver. In this case, since the air valve 24 and the bubble jet device 55 can be operated by the remote controller, a weak person can take a bath without a caregiver.

In addition, in this bathing assistance device 2, the float 2
In the state in which 0 is stopped from moving upward by the stopper member 23, air having a pressure higher than the atmospheric pressure is stored in the air reservoir 20a of the float 20, so that the bather M is
Even when getting on, the descending amount of the floating table 20 is small, and the floating table 20 can be sufficiently stabilized. Furthermore, in this bathing assistance device 2, the upper surface of the float 20 and the upper surface of the bathtub 5 are positioned substantially flush with each other via the stopper member 23, so that the bather M can easily get on and off the float 20. .

In addition, in this bathing assistance device 2, the float 2
Even if a force is applied to the end portion of 0, the float 20 hardly tilts due to the guide member 21 and the guide rail 22, so that the bather M can safely ride on the float 20 side. Moreover, it is possible to safely descend from the floating table 20.

The air valve 24 and the bubble jet device 5
The operation of 5 may be performed by attaching an operation panel to the side of the right wall portion 51 of the bathtub 5 and using this operation panel. Further, if the support plate portion 20a of the floating table 20 is made of a sheet member that is easily deformable, the bather M has his / her waist and back supported by air, so that the burden on himself / herself is reduced and the bather M is placed on the water bed. You can take a bath with the same feeling as when you went to bed. Furthermore, when the bather M takes a bath, hot water can be stored on the support plate 20a of the floating table 20.
It may not be necessary to lie on the cold support plate portion 20a.

Further, as shown in FIG. 9, if a part of the guide rail 22 is extended upward and the handrail portion 22a is attached thereto, the bather M can take a bath more easily. In addition, as shown in FIG.
If a support plate 56 that extends a little toward the float 20 is attached to the upper surface of the right wall portion 51 of the bathtub 5 on the side where the float 20 moves in and out of the float 20,
The inclination of 0 can be completely suppressed.
